NAILING INSERT.

Application filed March 27, 1925. Serial No. 18,822.

This invention relates to a nailing insert. It is particularly designed to be used in connection with brick work, masonry, concrete and the like.

The primary object of the invention is to provide a nailing insert which will guide nails, screws or the like in a straight line and prevent their turning or bending due to resistances set up in the masonry, brick work or concrete.

In carrying out the invention I may utilize a corrugated sheet of lead or some similar ductile material, the surface of which may, or may not, be coated with glue, sawdust or some other appropriate medium and in some cases the corrugated sheet may be provided with an enclosing casing in the form of a grid with two walls betweenwhich the sheet is received. The grid like walls of the casing permits mortar or concrete to flow be tween the spaces formed by the grid so as to act as an efiicient bond to hold the casing be tween the courses of brick or masonry, the casing, however, is not necessary in all instances. I

The novelty of my invention will be specifically described hereinafter, reference being had to the following description in connection with the accompanying drawings, in which I Fig. 1 a fragmentary, perspective view of one corner of a room constructed of bricks for the walls and concrete for the floor, the casin g with the corrugated sheet being sh own in the wall and the corrugated sheet alone being shown in the concrete floor.

Fig. 2 is a perspective View of gated insert.

Fig. 3 is a perspective view of a morhfied form of insert.

Fig. dis a perspective view of a further modified form of insert.

Fig. 5 is a sec-tional view through part of a concrete floor with the form of insert, shown in Fig. 2, imbedded therein and showing a nail partly driven into the concrete, and

Fig. 6 is a perspective sectional view of the corrugated sheet and casing.

In Fig. 2 I have shown a simple form of insert ascomprising a corrugated sheet 1 of lead although other material may be used, however, I prefer to use lead because it is soft,

the corrupliable and easily formed into sheets and because it is especially adapted for the purpose of lllfili-illlfeilillflllz The corrugated portions 2 and. 3 alternate so as to form guide grooves" 4 and 5 on opposite sides of the sheet 1. T he sheet is inserted endwise so that the nails, screws or the like may be driven longitudinal of the corrugations. The" corrugated walls serve as guides for the nails, screws or the like of the sheet with a suitable friction material, such as' glue, sawdust or the like. The coated sheet is best illustrated in Fig. 3. Here the sheet is rolled in cross section, one end 6 being in the center and the other end" 7 on the outside of the roll, the roll may beand whereverdesired I may coat the surfaces sheets 9, 10 and 11- (arranged substantially parallel.) are parts of one continuous sheet.

In Fig. 5 the form of insert (shown in Fig. 2) is illustrated as imbedded in the concrete base or mass 14. By concreteI mean any cementitious mass or body. In Fig. 5 I have also shown how the nail 15 may be driven into the concrete in asti'aight line, guided as it is in one of the grooves of the nailing insert. It will be apparent that liability of the nail turning or bending willbe eliminated because the entire longitudinal surface will be supported by the walls of the guiding grooves as the nail is driven in.

In Fig. 6 I have shown the strip or sheet I received in a holder or casing, the casing being illustrated as comprising a sheet of metal 16 bent intermediate its ends as at 17 to form two substantially parallel walls 18 and 19, the walls being slotted as at 20 and 21' so that the edges of the slots canbe turned outwardly, the free ends of the holder or casing being broughttoeether at 26, which is really the rear end of the casing. The casing is preferably used in connection with the sheet as an anchor where the nailing insert is to be placed between courses of brick or masonry in the mortar joints.

In Fig. 1 I have shown how the casings or holders are applied in the mortar joints 27 between the bricks 28. g

It will be seen from the foregoing thatI have provided a simple, i1iexpensiye,'easi1y constructed nailing insert which will prevent the nails from bending as they are driven into the hard wells andwhiie I have specifically described at this time what appears to me to be the very best forms of my invention I sheet, the corrugations providing angularly related walls constitutinnu nail uides n 3011 opposite sides of the sheet for irictionslly engaging the nail to prevent its separation from the sheet,-the corrugations being faced with iriction material.

2. A nail guide comprising a sheet having staggered longitudinal channels, the walls of the channels providing adjacent guides for nulls, and a holder therefor consisting of parallel bodies provided with slots disposed transversely to said channels of the sheet.

3. In combination with a nail guide, a holder comprising spaced slotted walls receiving the guide, the walls having outstru ck portions transversely disposed'to the axis of the guide, outstriking of said, portions producing said slot-s. i

In testii'nony whereof I affix my signature.
